Fit, and our day-to-day work philosophy is reflected in our four values:**Care:**We genuinely care for others whoever they are, whatever they think.**Excellence:**We aim to improve and achieve better results every day.**Humility:**Staying humble and exchanging transparent feedback helps us to grow and improve.**Passion:**We are the architects of Pay

Fit's success.

A key part of our **culture**, and essential for our success, is also improving the **diversity** of our teams and building an **inclusive** culture where you can be yourself at work.

This is why our recruitment focuses on the skills you demonstrate, and not only on your academic background or previous professional experiences. At Pay

Fit we understand that you can gain applicable skills through a variety of life experiences and we are interested in knowing them, too.**Location :** The position is based in **France or Spain.**#### **About the role**We’re looking for a **frontend-first full-stack engineer** to build and evolve the employee experience across our platform. **The Employee Management team** owns the key journeys where users create, manage, and update employee data throughout the employee lifecycle.

This is a **full-stack role aligned with team priorities**: you’ll contribute wherever the work is, across frontend and backend. At the same time, you bring a **strong frontend background** and will help the team level up on UI quality, frontend architecture, and product experience standards.##### **What you will do**

• Deliver product work end-to-end: discovery, technical design, implementation, rollout, iteration.
• Build high-quality, user-centric interfaces: accessible, performant, consistent.
• Take ownership of frontend architecture and patterns (state management, data fetching, routing, error handling, forms) to improve quality and speed sustainably.
• Collaborate on backend implementation when needed (services, endpoints, integrations) to ship team priorities.
• Improve our design system usage and help scale UI consistency across flows.
• Raise the bar on engineering quality through reviews, pairing, and pragmatic technical leadership.##### **Backend collaboration & API design**A key part of the role is ensuring the **end-to-end experience** is high quality. You’ll work with the team to design and evolve APIs that are:* predictable and consistent,* optimized for product usage (latency, pagination, partial updates),* resilient (validation, error semantics, backwards compatibility),* and easy to consume from the frontend.

You won’t be “the backend owner”, but you will be expected to contribute when needed and help drive API choices that directly impact user experience.##### **What we are looking for*** Strong experience building modern web apps with **React** (or similar) and **Type

Script.**

• Proven ability to deliver **full-stack** work, prioritizing the most valuable outcomes for the team.
• Strong product sense and **attention to UX details** (edge cases, empty states, error states, loading states).
• Ability to influence **frontend quality** and help others level up (patterns, reviews, examples, shared components).
• Comfortable collaborating with PM/Design and across engineering.##### **Nice to have**
• Experience with design systems/component libraries at scale.
• Frontend observability experience (error tracking, monitoring, performance metrics, web vitals).
• Experience in complex B2B workflows (permissions, audits, multi-step flows).
• Experience in improving the reliability and maintainability of a mature codebase##### **Why this role matters****Employee Management** sits at the heart of the platform. The quality of these journeys impacts daily workflows for customers and sets the bar for the rest of the product. This role combines strong ownership of team delivery with a clear mandate to elevate frontend quality and user experience.##### **Interview process :**1. Interview with a recruiter - **45min**2. Interview with Pierre (Tribe's Engineering Director) - **45min**3. Live frontend technical challenge case with 2 members of the team - **60min**4.
